No teens or mutant teens, take your pick: In the near future, Clive Owen, Julianne Moore, Michael Caine, and Chiwetel Ejiofor look to save the Earth’s last pre-born in the dystopic new trailer for Alfonso Cuaron’s Children of Men. (Between this and The Fountain, it may be a good fall for sci-fi.) And Michelangelo, Raphael, Donatello, and Leonardo (the turtles, not the artists) get the CGI treatment in the teaser for TMNT. (No Elias Koteas or Sam Rockwell this time around? Bleah.)
